blacks were concentrated in the lowest-paying, dirtiest, and most hazardous jobs, and were routinely harassed and assaulted. It was not enough to have separate bathrooms for blacks and whites; the "black" bathrooms were often located far from specific workplaces, forcing employees to spend a good deal of their break getting there and coming back. It was not enough to have separate water fountains for blacks and whites; the "black" fountains were never cleaned, and the water was always warm.
